21.4 Depth data monitor
MFDs configured to use the First responder profile will constantly monitor
the availability of depth data.
If depth data becomes unavailable (i.e.: lost) then the Depth measurement
lost alarm is triggered. If depth data is intermittent then the alarm will only be
triggered once every 60 seconds. The alarm will be automatically dismissed
when depth data becomes available again.
Note:
The depth measurement lost alarm is permanently enabled when using the
First responder profile and cannot be disabled.
21.5 Data logging
The Data Logger records, at regular intervals, readings taken by your vessel’s
equipment, an active Man overboard alarm, and the 5 closest AIS targets.
The Data logger is enabled by default and records data to a CSV file saved
to a MicroSD card inserted into a card slot on the MFD. A new CSV file is
created every hour up to a maximum of 73 files (72 hours of data), after which
the first file will be overwritten by the next new Data logging file.
If the MicroSD card is removed or reaches capacity, Data logging will be
suspended and a notification will be displayed onscreen.
Note:
• On MFD networks only the datamaster MFD can be used to perform
data logging.
• For optimal performance, Do NOT use cartography cards for Data
logging.
The status of the Data logger is displayed in the status area of the
Homescreen using icons.
1. Data logging active
2. Data logging error (e.g.: no MicroSD card inserted)
3. Data logging disabled
The Data logger records the following data, when available:

• Date and time
• Latitude and Longitude

• Depth
Man Overboard:

5 closest AIS targets:
